Description

Technical Field

[0001] Embodiments of this application relate to the technical field of control or regulation systems, and particularly to a control system suitable for irradiation devices. Background Technology

[0002] The statements herein are provided merely as background information in connection with this application and do not necessarily constitute prior art.

[0003] To evaluate the performance of materials after irradiation in a reactor, irradiation devices need to be installed in the research reactor to conduct irradiation tests. To conduct irradiation tests on materials under different irradiation environments, independent irradiation devices with different cooling media are required. After completing an irradiation test with one cooling medium, the existing irradiation device needs to be dismantled and a new one installed.

[0004] The control system of an irradiation facility is used to acquire parameters of the irradiation facility and the irradiation target, and to control the irradiation facility and the target. When replacing an irradiation facility, it is often necessary to disassemble and reassemble the control system as well. However, disassembling and reassembling the control system of an irradiation facility is quite difficult, which brings inconvenience to the replacement of the irradiation facility. Summary of the Invention

[0005] A brief overview of this application is provided below to offer a basic understanding of certain aspects thereof. It should be understood that this overview is not an exhaustive summary of the application. It is not intended to identify key or essential parts of the application, nor is it intended to limit its scope. Its purpose is merely to present certain concepts in a simplified form as a prelude to the more detailed description that follows.

[0006] Embodiments of this application provide a control system suitable for an irradiation device, which includes: a wireless communication unit, a conversion and transmission module, a controller, a server, a user operation station, and a user debugging station; The wireless communication unit is configured to receive instrument signals from the irradiation device and convert the instrument signals into wireless signals for transmission to the conversion and transmission module. The conversion and transmission module is configured to receive wireless signals from the wireless communication unit, convert the wireless signals into data that the controller can receive, and transmit the data to the controller. The controller is configured to determine the measurement point configuration and control logic of the irradiation device, determine the operating status of the irradiation device based on data, and control the operating status of the irradiation device based on the measurement point configuration and control logic, the operating status of the irradiation device, and control commands from the user's operating station; the controller is also configured to transmit data to the server. The server is configured to process data from the controller to determine the operating status information, process parameter information, and alarm information of the irradiation device, and to transmit the operating status information, process parameter information, and alarm information to the user operation station, and is also configured to transmit control commands from the user operation station to the controller. The user station is configured to receive operating status information, process parameter information, and alarm information from the server, as well as receive control commands input by the user and transmit the control commands to the server. The user debugging station is configured for debugging the wireless communication unit, conversion and transmission module, controller, and server.

[0007] The control system provided in this application converts the instrument signals of the irradiation device into wireless signals via a wireless communication unit, and transmits these wireless signals to the conversion and transmission module wirelessly. This allows for easy replacement of the irradiation device by simply disassembling and assembling the irradiation device and the wireless communication unit, installing a new irradiation device and wireless communication unit, and then wirelessly connecting the new wireless communication unit to the existing conversion and transmission module. This eliminates the need to remove and re-lay cables, significantly reducing the difficulty and increasing the efficiency of irradiation device replacement. Furthermore, because the controller is configured to determine the measurement point configuration and control logic of the irradiation device, after installing the new irradiation device and wireless communication unit and wirelessly connecting the new wireless communication unit to the conversion and transmission module, the controller can automatically determine the measurement point configuration and control logic of the newly replaced irradiation device. Based on this, the controller can control the operating status of the irradiation device, achieving plug-and-play functionality after replacement and avoiding reconfiguration and debugging after replacement, further shortening the debugging cycle after irradiation device replacement.

To simplify the disclosure of this application, specific examples of components and methods are described below. Of course, these are merely examples and are not intended to limit this application. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0015] In existing technologies, the control system of an irradiation device in a research reactor typically uses a wired design to transmit signals. The control system is connected to the sensors and other instruments of the irradiation device via cables, and various devices within the control system are also connected via cables. However, the dismantling and installation of cables during the removal and installation of the irradiation device is time-consuming, difficult, and costly, causing inconvenience for the replacement of the irradiation device.

[0016] To address the aforementioned problems, embodiments of this application provide a control system suitable for irradiation devices. Figure 1 This is a schematic diagram of the control system according to an embodiment of this application. Figure 1As shown, the control system 100 includes: a wireless communication unit 10, a conversion and transmission module 20, a controller 30, a server 40, a user operation station 50, and a user debugging station 60. The wireless communication unit 10 is configured to receive instrument signals from the irradiation device 200 and convert the instrument signals into wireless signals for transmission to the conversion and transmission module 20. The conversion and transmission module 20 is configured to receive wireless signals from the wireless communication unit 10, convert the wireless signals into data that the controller 30 can receive, and transmit the data to the controller 30. The controller 30 is configured to determine the measurement point configuration and control logic of the irradiation device 200, determine the operating status of the irradiation device 200 based on the data, and determine the operating status of the irradiation device 200 based on the measurement point configuration, control logic, operating status of the irradiation device 200, and control commands from the user operation station 50. The controller 30 controls the operating status of the irradiation device 200; the controller 30 is also configured to transmit data to the server 40; the server 40 is configured to process the data from the controller 30 to determine the operating status information, process parameter information, and alarm information of the irradiation device 200, and transmit the operating status information, process parameter information, and alarm information to the user operation station 50, and is also configured to transmit control commands from the user operation station 50 to the controller 30; the user operation station 50 is configured to receive the operating status information, process parameter information, and alarm information from the server 40, and to receive control commands input by the user and transmit the control commands to the server 40; the user debugging station 60 is configured to debug the wireless communication unit 10, the conversion and transmission module 20, the controller 30, and the server 40.

[0017] The control system 100 provided in the embodiments of this application converts the instrument signals of the irradiation device 200 into wireless signals through the wireless communication unit 10, and transmits the wireless signals to the conversion and transmission module 20 in a wireless transmission manner. This makes it possible to replace the irradiation device 200 by simply disassembling and assembling the irradiation device 200 and the wireless communication unit 10, installing a new irradiation device 200 and the wireless communication unit 10, and then wirelessly communicating with the original conversion and transmission module 20 without removing and re-laying cables. This greatly reduces the difficulty of replacing the irradiation device 200 and improves the efficiency of replacing the irradiation device 200. Furthermore, since the controller 30 is configured to determine the measurement point configuration and control logic of the irradiation device 200, after installing the new irradiation device 200 and the wireless communication unit 10, and wirelessly connecting the new wireless communication unit 10 to the conversion and transmission module 20, the controller 30 can automatically determine the measurement point configuration and control logic of the newly replaced irradiation device 200, and further control the operating status of the irradiation device 200 accordingly. This achieves plug-and-play functionality of the replaced irradiation device 200, avoids reconfiguration and debugging after replacing the irradiation device 200, and further shortens the debugging cycle after replacing the irradiation device 200.

[0018] In some embodiments, the wireless communication unit 10 is mounted on the irradiation device 200. In such embodiments, the wireless communication unit 10 can be removed and installed as a whole with the irradiation device 200, so that no signal cables need to be removed or installed when removing and installing the irradiation device 200 and the wireless communication unit 10.

[0019] In some embodiments, the wireless communication unit 10 is wired to the instrument of the irradiation device 200 to receive the instrument signals of the irradiation device 200.

[0020] In some embodiments, the wireless communication unit 10 and the conversion and transmission module 20 are configured to be wirelessly connected; the conversion and transmission module 20, the controller 30 and the server 40 are configured to be sequentially connected in communication; the server 40 is configured to be connected in communication with the user operation station 50 and the user debugging station 60.

[0021] In this embodiment, since the wireless communication unit 10, conversion and transmission module 20, controller 30, and server 40 are sequentially connected, and server 40 is connected to user operation station 50 and user debugging station 60 respectively, the instrument signals of irradiation device 200 received by wireless communication unit 10 can be converted into operating status information, process parameter information, and alarm information of irradiation device 200 through conversion and transmission module 20, controller 30, and server 40 and transmitted to user operation station 50. This allows the user to obtain information such as the operating status and process parameters of irradiation device 200 from user operation station 50. Furthermore, control commands input by the user from user operation station 50 can also be transmitted to controller 30 through server 40, and the user can also debug the entire communication link of control system 100 at user debugging station 60.

[0022] Since only the irradiation device 200 and the wireless communication unit 10 need to be disassembled and reassembled when replacing the irradiation device 200, without disassembling and reassembling other components of the control system 100, in some embodiments, the conversion transmission module 20, the controller 30 and the server 40, and the server 40 and the user operation station 50 and the user debugging station 60 can be connected by wired or wireless connections.

[0023] In some embodiments, the conversion and transmission module 20 includes a wireless gateway 21 and a communication module 22. The wireless gateway 21 is configured to be wirelessly connected to the wireless communication unit 10, receives wireless signals from the wireless communication unit 10, converts the protocol format of the wireless signals into a protocol format adapted to the communication module 22, and transmits the protocol-converted signals to the communication module 22. The communication module 22 is configured to be communicatively connected to the wireless gateway 21, converts the protocol-converted signals into data that the controller 30 can receive, and transmits the data to the controller 30.

[0024] In such an embodiment, the wireless gateway 21 can perform signal protocol conversion, and the communication module 22 can convert the signal into data that the controller 30 can receive and process, thereby enabling the data to be transmitted to the controller 30.

[0025] In some embodiments, the wireless transmission between the wireless communication unit 10 and the wireless gateway 21 employs encryption technology to protect the signal data transmitted between the wireless communication unit 10 and the wireless gateway 21, preventing the test data from being intercepted or lost.

[0026] In some embodiments, the wireless communication unit 10 is provided with an identification identifier corresponding to the measurement point configuration and control logic of the irradiation device 200; the wireless gateway 21 is configured to automatically read the identification identifier and transmit the identification identifier to the controller 30; the controller 30 is configured to determine the measurement point configuration and control logic of the irradiation device 200 based on the identification identifier.

[0027] In this embodiment, it can be understood that irradiation devices 200 using different cooling media correspond to different measurement point configurations and control logics, and the identification identifiers within different wireless communication units 10 correspond one-to-one with the measurement point configurations and control logics of each irradiation device 200. When connecting the wireless communication unit 10 to the wireless gateway 21, the wireless gateway 21 can automatically read the identification identifier of the wireless communication unit 10 and transmit the identification identifier to the controller 30. The controller 30 can determine the corresponding measurement point configuration and control logic of the irradiation device 200 based on the identification identifier, thereby automatically calling the corresponding measurement point configuration and control logic to achieve plug-and-play functionality of the irradiation device 200, avoiding reconfiguration and debugging after replacing the irradiation device 200, and further shortening the debugging cycle after replacing the irradiation device 200.

[0028] In some embodiments, the identity identifier of the wireless communication unit 10 is configured to be permanently stored in the non-volatile memory of the wireless communication unit 10.

[0029] In some embodiments, the wireless gateway 21 is configured to be paired and bound to the wireless communication unit 10, so that the wireless gateway 21 can only be wirelessly connected to the wireless communication unit 10.

[0030] In this embodiment, since the wireless communication unit 10 and the wireless gateway 21 are paired and bound, only the wireless communication unit 10 that is pre-paired and bound to the wireless gateway 21 can connect to the wireless gateway 21 during the irradiation test. This avoids incorrectly connecting other wireless communication devices that are not suitable for this irradiation test and improves the reliability of the control system 100.

[0031] In some embodiments, the controller 30 is configured to perform a cyclic redundancy check on the identity identifier before determining the measurement point configuration and control logic of the irradiation device 200, to determine that the identity identifier corresponds to the irradiation device 200.

[0032] In such an embodiment, performing cyclic redundancy check on the identity identifier before the controller 30 determines the measurement point configuration and control logic of the irradiation device 200 helps to ensure that the identity identifier received by the controller 30 has not been erroneous during transmission, thereby ensuring that the controller 30 can correctly determine the measurement point configuration and control logic of the irradiation device 200.

[0033] In some embodiments, the wireless communication unit 10 is configured to buffer instrument signals when the connection with the conversion and transmission module 20 is disconnected, and to convert the buffered instrument signals into wireless signals and transmit the wireless signals to the conversion and transmission module 20 when the connection with the conversion and transmission module 20 is restored.

[0034] In such an embodiment, when the wireless communication link between the wireless communication unit 10 and the wireless gateway 21 is interrupted, the wireless communication unit 10 can promptly buffer the received instrument signals. When the wireless communication between the wireless communication unit 10 and the wireless gateway 21 is restored, the wireless communication unit 10 can continue to convert the buffered instrument signals into wireless signals and automatically transmit them to the controller 30 through the conversion and transmission module 20, thereby ensuring the continuity and integrity of the irradiation test data.

[0035] In some embodiments, the wireless gateway 21 employs a hot standby redundancy configuration. In such embodiments, when one wireless gateway 21 fails, signal transmission is not affected, which helps ensure the operation of the control system 100 and improves the reliability of the control system 100.

[0036] In some embodiments, the communication module 22 employs a hot standby redundancy configuration. In such embodiments, when one communication module 22 fails, signal transmission is not affected, which helps ensure the operation of the control system 100 and improves the reliability of the control system 100.

[0037] In some embodiments, controller 30 employs a hot standby redundancy configuration. In such embodiments, when one controller 30 fails, other controllers 30 can take over to ensure the operation of the control system 100, thereby improving the reliability of the control system 100.

[0038] In some embodiments, controller 30 may be, for example, a DCS controller.

[0039] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0040] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. The scope of protection of this application shall be determined by the scope of the claims.
